Teff Grain-Based Functional Food for Prevention of Osteoporosis: Sensory Evaluation and Molecular Docking Approach.

Osteoporosis is a highly prevalent skeletal disorder, which is characterized by compromised bone strength predisposing to an increased risk of fracture. The medical approaches presently followed for the prevention and treatment are associated with several side effects. Thus, it becomes important to design alternatives that are safer, economical, and easy to use. Plants provide us with a beneficial and effective option for such designs. They are rich in nutrients and phytochemicals that can be used to target signalling pathways to prevent the development of disease. For this purpose, we used Ethiopian grain, teff as a preventive strategy for osteoporosis as it has a favourable nutritional profile. In our study, we focussed on the preparation of functional multi-grain flour with Ethiopian grain, teff, and other ingredients that have a positive effect on bone health. A cookie was prepared from the multi mix flour and to analyze its shelf life and acceptance we performed a sensory evaluation where we observed no significant difference in the cookies' characteristics during the period of study. We also performed Molecular Docking of eight flavonoid polyphenols selected from the nutritional profile of the ingredients to understand their binding affinity, interaction with the target, receptor activator of nuclear factor kappa-Β ligand (RANKL), and prophylactic or therapeutic effects in the prevention of osteoporosis. It was found that all 8 flavonoid polyphenols bound with RANKL, at least at one of the crucial binding sites and so can be used for the prevention of osteoporosis.
